(C) In linear motion,work done is given by $W = F \Delta x$. The rotational analogue of force $F$ is torque $\tau$,and the analogue of displacement $\Delta x$ is angular displacement $\Delta \theta$. Thus,the rotational work is $W = \tau \Delta \theta$. This corresponds to $(1-b)$.In linear motion,power is given by $P = Fv$. The rotational analogue of force $F$ is torque $\tau$,and the analogue of velocity $v$ is angular velocity $\omega$. Thus,the rotational power is $P = \tau \omega$. This corresponds to $(2-a)$.Therefore,the correct matching is $(1-b), (2-a)$.
